Through the limit installation component, this utility model facilitates the staff to move and limit the position of the mounting seat, thereby facilitating the staff to adjust the position of the mounting seat according to needs, and further facilitating the staff to install the refrigeration chip body. At the same time, it is convenient for the staff to protect the fixing bolt used during installation and can also limit the redundant part of the connecting wire.

Since the semiconductor refrigeration chip is directly fixed to the installation surface by screws, the installation structure is single, the cooling range of the semiconductor refrigeration chip is relatively limited, and the screw installation method also makes the disassembly and assembly of the semiconductor refrigeration chip inconvenient. Therefore, we propose a refrigeration chip assembly for a refrigeration device to solve the above problems. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] In order to further explain the technical solution of the utility model, the following is elaborated in detail through specific embodiments.

[0023] Please refer to Figure 1-2 , the utility model provides a refrigerating sheet assembly of a refrigeration device, including a refrigerating sheet 1, a power supply wiring 2 and a multi-functional installation structure 3. The front part of the refrigerating sheet 1 is connected with the power supply wiring 2, and the multi-functional installation structure 3 is arranged outside the refrigerating sheet 1.

[0024] Please refer to Figure 3-6, the present utility model provides a thermoelectric cooler assembly for a refrigeration device. The multi-functional mounting structure 3 includes a lower support 31, a mounting cavity 32, an upper support 33, a connecting cavity 34, a spring telescopic rod 35, an opening 36, heat dissipation fins 37, a hook 38, and a rotating frame 39. An installation cavity 32 is provided on the top surface of the lower support 31. The thermoelectric cooler 1 is placed inside the installation cavity 32. The upper support 33 is located directly above the lower support 31. A connecting cavity 34 is provided on the bottom surface of the upper support 33. The upper support 33 is buckled on the surface of the lower support 31 through the connecting cavity 34 and pressed on the top of the thermoelectric cooler 1. Among them, the cold end of the thermoelectric cooler 1 is in contact with the lower support 31, and the hot end of the thermoelectric cooler 1 is in contact with the upper support 33. Spring telescopic rods 35 are installed at the four corners of the outside of the upper support 33. The bottom ends of the spring telescopic rods 35 are fixedly connected to the lower support 31. The upper support 33 is elastically connected to the lower support 31 through the spring telescopic rods 35. Openings 36 are provided at the front parts of both the lower support 31 and the upper support 33. The power supply wiring 2 passes through the opening 36 and extends outwards. Heat dissipation fins 37 are installed on the top of the upper support 33. Hooks 38 are symmetrically arranged on the left and right sides of the upper support 33. Rotating frames 39 are hingedly installed on the left and right sides of the lower support 31. The rotating frames 39 can be turned upwards and buckled into the inside of the hooks 38, thereby clamping the upper support 33 to prevent the upper support 33 from bouncing up by itself.

[0025] Furthermore, both the lower support 31 and the upper support 33 are made of thermally conductive metal materials. Copper metal can be used. The excellent thermal conductivity of copper metal enables the lower support 31 and the upper support 33 to have excellent thermal conductivity efficiency, ensuring the refrigeration effect of the thermoelectric cooler 1.

[0026] Furthermore, the bottom area of the lower support 31 is not less than 1.5 times the area of the cold end of the thermoelectric cooler 1. The lower support 31 can expand the refrigeration range of the thermoelectric cooler 1 and the installation surface.

[0027] Furthermore, solid silicone grease sheets 310 are laid on the bottom surface of the installation cavity 32 and the top surface of the connecting cavity 34. The solid silicone grease sheets 310 can reduce the thermal resistance between the thermoelectric cooler 1 and the lower support 31 and the upper support 33, thereby improving the refrigeration efficiency.

[0028] Furthermore, the maximum distance between the upper support 33 and the lower support 31 is not less than 2 times the thickness of the thermoelectric cooler 1, ensuring that the thermoelectric cooler 1 can be disassembled and assembled smoothly, and the operation is simple and convenient.

[0029] Furthermore, a protrusion 4 is provided on the right side wall of the thermoelectric cooler 1, and a groove 41 is provided on the right side wall of the installation cavity 32. And the protrusion 4 can be butt-jointed and buckled with the inside of the groove 41. Through the cooperation of the protrusion 4 and the groove 41, it can prevent the user from installing the upper and lower sides of the thermoelectric cooler 1 in reverse, ensuring the installation success rate.

[0030] The working principle is as follows:

[0031] First, by setting up the multi-functional installation structure 3, first screw-fix the lower support 31 to the installation surface, and then install the thermoelectric cooler 1. The specific operation process is as follows: Turn out the rotating frames 39 on both sides of the lower support 31 from the inside of the hooks 38 to release the fixation between the lower support 31 and the upper support 33. At this time, the upper support 33 will bounce upward under the elastic force of the spring telescopic rod 35, increasing the distance between the upper support 33 and the lower support 31. At the same time, the connection cavity 34 is exposed. Then the thermoelectric cooler 1 can be placed inside the connection cavity 34. After confirming that the thermoelectric cooler 1 is stably placed, press down the upper support 33 so that the upper support 33 is buckled on the surface of the lower support 31 through the connection cavity 34 and pressed on the top of the thermoelectric cooler 1. The power supply wiring 2 then passes through the opening 36 and extends outwards. Finally, turn the rotating frame 39 upwards and buckle it into the inside of the hook 38 to fix the upper support 33, so that the thermoelectric cooler 1 is fixed between the upper support 33 and the lower support 31, and the installation is completed. The installation operation of the thermoelectric cooler 1 is simple and convenient, without the need to use external tools, and the installation efficiency is high.

[0032] Second, by setting up a protrusion 4 on the right side wall of the thermoelectric cooler 1 and a groove 41 on the right side wall of the installation cavity 32, through the cooperation of the protrusion 4 and the groove 41, it can prevent the user from installing the thermoelectric cooler 1 upside down, ensuring the installation success rate.

[0033] Third, during the use process, connect the power supply wiring 2 to an external power supply to supply power to the thermoelectric cooler 1, so that the cold end at the bottom of the thermoelectric cooler 1 absorbs heat and the hot end at the top releases heat. The thermoelectric cooler 1 absorbs the heat of the installation surface through the lower support 31, and then transfers the heat to the heat dissipation fins 37 through the upper support 33, and then the heat dissipation fins 37 release the heat into the air, thereby realizing refrigeration and heat dissipation. Among them, the bottom area of the lower support 31 is not less than 1.5 times the cold end area of the thermoelectric cooler 1, and the lower support 31 can expand the refrigeration range of the thermoelectric cooler 1 and the installation surface, ensuring the refrigeration effect of the thermoelectric cooler 1.

Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
